Lyonmum I wouldn't go turning to medication just yet - may be in a month if you still feel the same way.
Think of how well you have done as a family to springboard your DS off to a good start in life. No mother wants their DC tied to their apron strings - its a good time for them to go and a safe way to do it. I do think universities are a safe context for these young ones to grow up - quite apart from the intellectual stimulation.
It has definitely been harder for me to let go of DS this year- firstly I have had him home for 3 months and secondly I am worried about him because he failed his first year. Last year I tried ever so hard not to be a helicopter mum and he used to be touchingly concerned at how I was managing without him to find my glasses. This year he is in a student house with friends which is OK and clean but not fantastically well appointed, but he has yet to make it down to his university to even firm up his modules though I am annoyed to see that he has joined the boxing club. Though I am proud that he arranged a freshers bop event in the JCR for yesterday.
Boxing club , of all things, I ask you how is that going to help him unless some terrorist organisation has recruited him? Heaven help us, or perhaps it is a response to the rough area his student house is in, again heaven help us. I mean the British Medical Association put out a statement against boxing some years ago as it caused brains to pulp. Not great.
Just now I realised I had rung him 7 times already today- first to wake him up at 1.30 ( he says he was the first in the house to wake up- not reassuring) and then to make sure he got up and went in to get his modules confirmed. Then I realised I was going over the top with anxiety. So here I am on mumsnet. I think now I have had my say I am off to keep busy as that, and thinking positive are the things which pull me through. I wish all other empty nesters well.
